Thank you PK,
Looking at the photos has made it easer, and yes i too would definitely use magnets in this case.

I mounted a receiver directly to a speaker box with velcro with no ill effects.

Martin555 asked me for photos of the cabin roof that this enquiry refers to and that’s what I provided.
Thanks for all the help and replies 👍

Will not be a problem with Magnet application for superstructure
Bill 👍

Hi Zooma.
Totally agree.
Have used the elastic band from boyhood years and it works well.
Magnets are the modern alternative,and never go ping and are more secure.Also never need to replace them.
Bill 👍

Errant pics 'put in their place' Bill 👍

"works well as long as the elastic band is strong enough for the particular application and is replaced before it has time to perish"
... and it doesn't 'PING' off into the lake 😮😠

R/C is
AUSTAR AX6S 2.4G 4CH Transmitter Radio Remote Control & Receiver

Ground testing radios with longer aerials such as the 27meg, and 40/41 meg radio systems should be done with the aerials fully retracted to reduce the effective range before walking way from the model to perform the test.
Some 2.4 gig systems (such as Spectrum) have a range reduction button that can be depressed to give the same range reducing effect.
Pre-arranged hand signals with a "helper" are essential to establish what is going on when the model is too far away to observe the response by eye.

The elastic band and hook idea has been used for many decades and works well as long as the elastic band is strong enough for the particular application and is replaced before it has time to perish.

No Pk! 😀
Not with today's digital receivers.
In the old days close to analogue tuning coils they might have messed things up a bit, but not nowadays. 😉
On my Sea Scout I used 5mm diameter neodymium magnets to hold down the cabin roof and the aft hatch deck. Haven't lost one yet 😊
Cheers, Doug 😎

Sorry.
Not sure where the two pictures have come from,but not posted by me.

No adverse reaction to magnets to date using various and different r/c systems.

All of the models have been electric powered and all have used 2.4gig radio systems.

That’s the main cabin roof

Hi PK.
I would suggest...Definitely NOT.but
What frequency are you going to run on?
Place the RC as far away from any form of interference as you can under any normal circumstances.
Older RC have much longer aerials which need to be placed much further away from interference.
Newer systems have a short stubby aerial.
Bill

Would magnets have any effect to the R/C signal?

I agree with Mike.
Magnets in my opinion are by far the best tool.
Whilst the ever faithful elastic band is safe and secure,they can be restrictive.
Bill

Hi PK,
Do you have a photo of the Roof/Superstructure that you want to secure ?
It would make it easer to come up with some suggestions.

Martin555.

Thanks
I did consider that and why not it’s easy to fit and allows easy access
👍

Hi PK l have a rubber band fitted on the inside of the cover then fitted to a form of hook that is securely attached to the boat itself. stops the cover from lifting and is really easy to lift to gain access to a cabin or a hold May not suit if it needs to be on show but has worked for me.

I fitted one 2mm brass rod to pass through the top of the front windscreen into the base of the front cabin roof.

This worked well, so I repeated this to retain the removable central wheelhouse roof and the rear cabin roof too.

The small bent ends gave me something to pull them back out with when I needed to remove any of the cabin tops, and they were small enough not to be conspicuous.

Having had a good fitting cabin roof blow off of my Rapier during a high speed run, I fitted some brass rod with small right angled bends on the end to make them easy to push in and pull back out again.

This was a good mechanical fix that never failed, but I have now changed them for recessed magnets that i hope will work as well when I am able to get back to the club lake again this season.

Use magnets, they are available in all sorts of sizes to suit any application - try EBay
